I am writing this review to warn others 5hat the rating may be skewed because this company will give you 30$ if you write a review in 10 days. I love the bike so far but I was not able to get 33km on one charge. Barely 12km. You have to be soooo careful with the throttle handle because it is a natural way to grab and hold the bike while you get on or off and zoom the bike leaps away. I held on but it popped a wheelie and the light on back broke. Second time I reacted more quickly. I plan to put red tape on the handle. Seat is very comfortable. It is heavy but seems like good quality.
Bought the Blutron ebike today. Assembly was very straightforward. Just needed to adjust the seat and hand brakes. Battery was fully charged. Noticed that the brakes squeaked a little bit. Hopefully will dissipate on it's own or may need to grease it a little. The supplied wrench was very cheap and bent out of shape within a few turns. Overall my son is very happy with it and all his friends have one as well. Much better than the Jetson ebike. Will buy another one soon. Only disappointment is that I was not able to purchase an extended warranty. It only has a 1 yr manufacturer's warranty. Hope this helps anyone who is interested in this purchase.
I am a little heavier than nominal weight, but it still pulls me up our fairly steep hill without much pedal power. The controls are very accessible and you can always power down to settle into normal pedal power. The speed control seemed fine: not too fast (so you can react) and not too slow (it does not take forever). Three speeds are very convenient.
